Using the Kepler space telescope, NASA astronomers have found the first planet that they believe to be made of rock, roughly equivalent in size to Earth and potentially capable of supporting life.
The planet, Kepler-186f, orbits the star Kepler-186 some 490 light years away in the constellation Cygnus. It has a diameter of 8,700 miles, making it larger than Earth, and its orbit lies within the “Goldilocks zone” where temperatures could allow for liquid water to flow on its surface. Kepler-186f likely even boasts similar gravity. It’s the first such planet to ever be discovered outside of our solar system.
so very cool
